Definition and Fidelity

The Manley Stereo Variable Mu Limiter Compressor is solely built to add definition and fidelity to individual tracks, stereo buses, or an entire mix. The classical, transparent character which the Variable Mu has to offer makes this compressor perfect for infusing warm harmonic content into your audio, free of audible compression artifacts.

Parameter Linking

The Manley Stereo Variable Mu Limiter Compressor features parameter linking to allow adjustments of two channels with stereo signals simultaneously. The integrated high pass sidechain filter can also prevent compression response to frequencies lower than 100 Hz so that you can maintain punch and clarity in the low-end. The Variable Mu also offers plug-in-only controls such as headroom and dry/wet mix. This provides easy access to parallel compression ideal for quickly polishing background vocals or a drum bus, whilst the headroom control lets you adjust the Variable Mu’s level to your preference.


"I had the opportunity to use the Variable Mu in a friend's studio a few years back. I was immediately smitten with the impact it had on my songs then and vowed to save my pennies to get one for myself one day. That one day arrived last week. Having worked on a few mixes since it arrived on Friday, I want to let you know that I am every bit as happy with it as I imagined I might be.

It's a pleasure to work with equipment that sounds this good.

Thanks so much for your commitment to excellence in audio. The world is a better place for it."
